Fraud patterns
Spot repeat uploads, duplicate receipts, and setups that make a receipt game easy to game.
Protect your prize stock without refusing honest shoppers. Most abuse shows up as repeats: the same receipt, the same shop, the same correction.
The same receipt keeps coming back
Why this happens: a shopper uploads one receipt several times, or shares it with friends.
Fix it: OmniLab marks a receipt as Duplicate when its details match one already uploaded, even a new photo of the same receipt. A duplicate doesn't count until your team approves it: compare it with the first one, and refuse repeats. See Receipt statuses.
Your team keeps correcting the same shop or amount
Why this happens: either a rule doesn't match your terms, or someone is testing the limits.
Fix it: first check the shop and amount rules match your terms. If they do, watch that shop's receipts more closely.
Weak receipts win valuable prizes
Why this happens: Amount or Merchant isn't required, and Automatic validation approves what it reads.
Fix it: require the fields the prize depends on, and use Manual validation for valuable prizes. See Validation policy.
Prevent it before launch
- Keep shop, amount and zip code rules in line with your terms.
- Use Manual validation for valuable prizes.
- Test a few bad receipts before launch: see Test the receipt flow.
